Pool Definition Facility

Control-M/Tape Online Pool Definition screens enable you to view, create and modify pool definitions.

Pools are logical groups to which media are assigned (for example, a pool can be defined for each department in your organization). Pools can help in the accounting of media per department, in departmental security, and in managing multi-platform media. Pools can be particularly useful for allocating and budgeting removable media by department. Scratch volumes are generally allocated on a pool basis. Control-M/Tape tracks the number of scratch volumes per pool so that a scratch volume is always available when needed.

Pool definitions are stored in libraries (partitioned data sets). A library contains pool tables (members), and each table contains specifications for one or more pool definitions. Most sites designate a primary pool definition library (the default is member $$POOL in the PARM library).
